,ANTIGLARE DEVICE.

Applcationled September 19, 1925.

T 0 all whom t may con-cern.:

Be it known that I, IVILLIAM S. ALLEN, a citizen of the United States,residing at Birmingham, in the county of Jefferson and State of Alabama,vhave invented certain new and useful Improvements in Ant-iglareDevices, of which the following is a specification.

My said invention'relates to an automobile headlight anti-glare deviceand it is 'an object of the inventionto provide a device of thischaracter which may be easily attached, of simple and durableconstruction, and inexpensive to manufacture.

Referring to the` accompanying drawings which are made a part hereofandon which similar reference characters indicate similar parts,

Figure 1 is a vertical longitudinal section of a headlight having myinventionapplied thereto, A

Figure l2, a rear elevation of the invention as it appears when applied,

Figure 3, a detail view of a metallic fastener,

Figure 4, a view similar to Figure 2 of a modifie-d form, of theinvention, and

rFiguref'), a vertical sefction of the modified form shown in Figure 4.Y f

In the drawings I have shown a headlight consisting of a light 10 and areiiector 11. A lens 12 is also supported in any desired manner at thefront of the reiiector 11. The foregoing structure4 is common inautomobile headlights and forms no part of my invention.

My invention comprises a device adapted to be used in conjunction with alight of the above character to afford a distinct improvement inappearance and to soften, tone, or obscure the glaring or very brightlight without sacrificing itsV effectiveness. A disk 13 of'celluloid orother material preferably colored is folded through its diameter to anacute angle and the said disk is placed behind the lens 12 and closelyadjacent thereto. The disk is positioned on the lens so that the centerof the arc of the disk or the locus of points of the radii is disposedat thecenter of the lens and the disk is above the horizontal diameterof the lens so that the straight or forward rays of light will pass in asubstantially horizontal plane underneath the disk and illuminate theroadway while the bright rays, which would normally Serial No. 57,435.

blind the eyes of a motorist approaching in the opposite direction,"will strike the rearinclin-ed surface of the wing of the disk nearestthe light and be reflected backupon the reflector 11 and thence in ahorizontal direction along the roadway. The angular portions of the diskare held in fixed relation by means of' a metal clip 14 havingpointedend portions 15 which are stuck through small slots in the diskand Vbent down to hold them in fixed relation. The disk is supported `onthe lens 12 by means of spring fasteners or cross wires 16 and 17secure-d by hooks 18 or other fasteners over the edge of the'lens. Thevertically disposed spring fastener 16 extends through a` small openingin the center of the disk and through a similar opening 19V in the clip14. The fasteners 16 and 17 are also provided with coiled portions 2Oand 21, respectively. The coiled portion 2O is below and serves as asupport for the disk 13 while the coiled portion 21 Yis disposed alongthe fold of the disk. Such arrangement permits only a very slightlateral movement of the disk due to the spring action as well as only aslight downward movement against the upper end of the spring' 20. Thehorizontally disposed spring vfastener 17 is disposed in the lbase ofthe angley between the folds of the disk and holds the diskagainst'thelens, the two spring fasteners disposed in crossed relationcompletely maintaining the disk in position.

If desired, the horizontal wire or support 17 `may be omitted and thestructure shown Y in Figures 4 and 5 used instead. In this form of theinvention a. vertical wire or support 22 is provided with the usualattachments or clamps 18 for the lens and the spring portion 23 isdisposed between the wings and between themetal fastener or clip 14 andthe opening in the center of the disk. Such structure will cause thedisk to be maintained in proper position on account of the engagement ofthe metal fastener 14 with the upper end of the spring portion 23 andthe opening through the center of the disk will permit tensioning of thespring downward through the opening. This will greatly simplify theattachment and reduce the cost of manufacture.

In operation only the very bright rays of light will be intercepted,theI less brilliant side rays passing out uninterrupted around the disk13 and the bright rays will 'be softened as they j iass through the diskand some of the light will be reflected back upon the reflector andthence on a sulr=tantially horizontal line ahead on the roadway.

It will be obvious to those skilled in the art that many changes ma)T bemade in my device without departing` from the spirit of the invention,and therefore l do not limit myself to what is shown in the. drawingsand described in the specification but only as indicated in the appendedclaims.

Having thus fullv described in v said invention, what lf claim as newand desire to secure by Letters Patent is:

i. An anti-glare device for headlights comprising a colored translucentdisk of thin material folded along its diameter rear* 'ardlv upon itselfand adapted to be supported adjacent the central portion of the lens ofthe headlight in inverted position with one wing of the disksubstantially parallel to the lens and the other wing extending at anangle thereto, and means for sup porting said disk, substantially as setforth.

An anti-glare device for headlights comprising a colored translucentdisk of thin material .folded along its diameter rcarwardlv upon itselfand adapted to be snpported adjacent the central portion of the lens ofthe headlight in inverted position with one wing of the disksubstantially parallel to the lens and the other wing extending at anangle thereto, and means for supporting` said disk, said means includingspring :fasteners engaging said disk and the lens, substantially as setforth.

3. An antiglare device for headlights comprising` a colored translucentdisk of thin material folded along; its diameter rearwardljfY uponitself and adapted to 4be snpported adjacent the central portion of thelens of the headlight in inverted position with one wing of the disksubstantialljT parallel. tothe lens and the other wing extending; at anangle thereto, and means for supj'iorting said dise, said meansincluding spring fasteners disposed substantially at right angles toeach other and closeljT adjacent the lens, t-he ends of :aid fastenersextending around the periphery of the lens and supporting the diskadjacent their point of intersection, substantially as set forth.

lt. An anti-glare device for headlights comprising a colored translucentdisk of thin material folded along its diameter rearwardlv upon itselfand adapted to be supported adjacent the central portion of the lens ofthe headlight in inverted position with one wing of the disksubstantially parallel t-o the lens and the other wing extending ai; anangle thereto, means for support-- ing said disk, and a clip holding thesides` of the disk in spaced angular relation, substantially as setforth.

5. The combination of a light, a reflector for said light, a lens forsaid reflector, a fastener extending` across the inner' face of saidlens, a second fastener extending across said inner face and at an angleto the irst mentioned fastener` a plate supported adjacent the.intersection of said fastenerrs in substantially parallel relation tothe lens and having a portion extending at an angle rearwvardljTtherefrom and forming a reflecting surface` said plate having asubstantially straight edge adjacent the center' of the lens,substantially as set fort-h.

t. The combination in a headlight of a lens, a fastening elementextending across said lens, a second fastening element extending' acrosssaid lens transversely of tho first mentioned fastening element, a diskfolded along its diamete.' and having a clip holding its sides in spacedangular relation, one of said 'fastening elements being disposed alongthe diameter of the disk along` which it is folded, the other of saidfastening elements extending through the center of said disk and throughsaid clip, substantially as set forth.

7. The combination in a headlight of a lens, a fastening elementextending across said lens, a second fastening element extending acrosssaid lens transversely of the first mentioned fastening element, a diskfolded along its diameter and having a clip homing its sides in spacedangular relation, onel of said fasteningl elements being disposed alongthe diameter of the disk along which it is folded the other of saidfastening elements extending through the center of said disk and throughsaid clip, and springs 1n said fastening elements, substantially as setforth.
